It all depends on what you want to do. I personally think the L-tube would be all you need. Reading here I thought eventually I would have to get the top shelf Provari. But one of my friends and local
juice supplier even told me, with this Vtube, I really don't need a provari. It basically does the same thing. Sure one may run at a few higher watts or something but for th emost part they will both do what you want from them. Now that I use my Vtube, I don't really see the need to get a Provari.. but never know what the future may bring.
